Abstract: A wall construction block for the construction of earth retaining walls includes a pair of spaced-part transverse pin receiving channels in the end walls of the block and disposed parallel to one another along respective longitudinal axis of the block which are parallel with a front face of the block.  The pin receiving channels extend transverse from a top surface to a bottom surface of the block and are of substantially uniform cross-section throughout. Arresting pin elements are received in sliding fit within some of the receiving channels and are retained captive therein. Elongated parallel grooves are provided on a top surface of the block and extend across the end walls and parallel to the front wall. One of the groove is aligned between a first set of the pin receiving channels and the other of the parallel grooves is offset a predetermined distance between the other set of pin receiving channels. When the blocks are disposed in rows one on top of one another, with the top wall of the block facing upwards, the rows of blocks are arrested from transverse shifting by positioning arresting pin elements in selected ones of the sets of transverse pin receiving channels. The pins extend out of the bottom wall of the uppermost block and into a selected one of the pair of grooves in a top surface of the lower block.

Granted: 2007-08-07
Abstract: In a method for predicting harmonic-distortion values for the application of a desired step change of capacitance to an AC system, an initial step change is applied and, from this change, a value of harmonic impedance of the system for each of a number of harmonics is determined. From these harmonic-impedance values corresponding values of damping resistance are, in turn, determined and, using the determined harmonic- impedance and damping-resistance values, corresponding values of an electrical load parameter, preferably load voltage, are determined for the desired step capacitance change. The method is conveniently extended to cover a method and apparatus for applying power- factor correction capacitance, in which the load-voltage values for the various harmonics are evaluated to see if they represent a potential resonance condition and, if so, a step change other than the desired change is applied. Where no resonance is indicated, the originally intended step change is applied.

Title: Call related information receiver to receiver transfer
Inventor: CANNON JOSEPH M
IPC: H04M1/2757
Filed: 2000-03-22
Granted: 2004-06-01
Abstract: A call related information detector/receiver system which is capable of downloading call related information received at that device to another call related information detector/receiver system remote from the system which initially received the call related information, back over the telephone line. Thus, a remote user while away from the home or office can receive and synchronize call related information at a system other than the one which initially received the call related information. Thus, a remote user can update a local call related information system and review past callers to their home or business telephone at their leisure. Upon establishment of a telephone call between customer premises equipment respectively associated with the two relevant call related information detector/receiver systems, a remote call related information system will request download of call related information logged from another call related information system using the established telephone call. In the disclosed embodiment, the request signals are encoded with DTMF tones, which the receiving call related information system monitors for. Upon acceptance of a request to transmit logged call related information, previously logged call related information is retrieved from its log, formatted for transmission together with suitable header information such as the identity of the transmitting call related information system, and FSK modulated for transmission back over the telephone line. Preferably, the speaker or earpiece of off-hook customer premises equipment will be muted or suppressed during transmission of the data corresponding to the call related information. The particular call related information transmitted may be particularly or generally requested by the remote call related information system, either by pre-stored commands based on a power up configuration of the requesting call related information system, and/or in response to a direct command input by the remote user using DTMF tones.

Title: Low volume fraction metal matrix preforms
Inventor: SANTOS RAUL
IPC: C22C1/10
Filed: 2000-08-31
Granted: 2006-10-03
Abstract: A process for making a low volume fraction preform for a metal matrix composite, wherein the metal is typically magnesium, aluminum and alloys thereof , and the reinforcement comprises either whiskers, fibres, tow or particulate, typically chosen from silicon carbide, graphite, carbon, silica, alumina, titanium diboride, boron nitride and boron carbide. The resulting preform has sufficient strength both to be handled, and to be infiltrated with liquid metal, for example by a squeeze casting process. A particular selection of binder material and sacrificial fillers is used to make the preform. In the first step, the reinforcement is mixed with a binder, and with sacrificial fillers, to provide a castable slurry which is then placed in a mould, to provide a green cast preform. In the second step, the green casting is dried, to remove any water and/or solvent remaining from the castable slurry. In the third step, the green preform is fired at a relatively low temperature, to burn off the sacrificial fillers. In the fourth step, the green preform is fired at an elevated temperature sufficiently high to sinter the binder to bond the reinforcement together. In the third and fourth steps particular combinations of temperature and time are used to ensure decomposition of the sacrificial fillers, followed by firing of the binder to sinter it and thus bond the preform together without destruction or cracking of the green preform. This process can also be used to provide low volume fraction preforms, so that the metal matrix composite contains less than about 8% by volume of whiskers, or less than 15% by volume of particulates.
